There is an interesting project that gets data from http://tibia.wikia.com and exposes this data using a RESTful JSON API. Maybe it can be useful for you. I didn't try it yet, but you can get a look here: https://github.com/benjaminkomen/TibiaWikiApi/
Alternatively, you could use Tibialyzer's SQL database. It is extracted from the tibiaWiki articles but nowadays it can be a bit outdated: https://github.com/Mytherin/Tibialyzer
